Abstract: PROBLEM TO BE SOLVED: To reduce a parasitic capacitance between data wiring and gate wiring and a pixel electrode, without causing degradation in display quality due to attenuation of incident light or drop of transistor characteristics. SOLUTION: On a transparent insulating substrate 1, a gate wiring 2a, a gate electrode 2b, a gate insulating film 3, and a semiconductor layer 4 are formed.
